Hi All I have a HP desktop i5 with a GT220 in it. Love it cause it's so damned quiet. Ideal cause i have it in my room. But with new GFX available and getting cheaper all the time...was wondering if it wasn't time for an upgrade. The XFX 5670 512ddr5 according to test/reviews is 3x as fast/powerfull as the GT220. In toms list its like 3 srteps above it. Another big plus...i currently have a 300watt HP PSU. And that seems to be enough for the 5670. The 5670 will cost me about 50€. is this a worthwhile upgrade? It really surprised me that it was 3x as fast compared to the 220gt. Or did i read wrong? Ofcourse when i buy a new PSU it opens all other GFX options like the 5750, €100. Ofcourse need to add PSU price too. Hope people can help me with my decision.
